CROSS REFERENCE TO RELATED APPLICATIONS

This application is the national phase entry of International Application No. PCT/TR2015/050191, filed on Nov. 23, 2015, which is based upon and claims priority to Turkish Patent Application No. TR2014/14155, filed on Nov. 27, 2014, the entire contents of which are incorporated herein by reference.

TECHNICAL FIELD OF THE INVENTION

The present invention relates to hygienic products such as sanitary pads, bladder pads, tampons, patient and baby diapers which are made antimicrobial and antiviral.

BACKGROUND OF THE INVENTION

Use of hygienic products for children, patients and women in the world has been observed to increase as the social life has developed and conventional methods have been abandoned. Since these products are not sterile and antimicrobial, microorganisms can easily proliferate in these media which are damp and include nutrition, and thus may cause important diseases in people. The content of the blood discharged from the bodies of women during menstruation provides a suitable medium for reproduction of microorganisms. These microorganisms reproduce on the hygienic pads or tampons used by women during menstruation period and cause serious diseases that threaten health. In addition, diapers fastened to the babies who cannot control their bladders and bowel movements or patient/aged diapers used by patients who are in need of care are also suitable reproduction media for opportunistic pathogens.

Especially in women using sanitary pads, infections that may occur due to closeness of the reproductive organs to the bowels and urinary tract anatomically cause a threat to the reproductive organs. While the fact that the vagina has low pH during normal times and that there is a form obstructing passage from the urethra to the bladder minimizes vaginal infection risk, a suitable medium is formed for reproduction of microorganisms because the menstruation blood is rich in nutrients during menstruation period and normalizes pH level of the vagina. Formation of a suitable medium for reproduction of microorganisms, rich nutrients in the blood and the dampness on the pad that is used increase infection risk. If the pads that are used are not frequently replaced, infections of reproduction system and urinary tract are encountered. In order to prevent infections and the odor occurring in long term use of pads, pads should be preventing microbial growth.

Tampons, which are another product used by women during menstruation period, retain the blood discharged from the body through vagina during menstruation period just like hygienic pads. Vaginal tampons, differing from the sanitary pads, enable absorbance of the blood before the blood is discharged out of the vagina. Factors that make social life of women difficult as a result of use of pads can be eliminated by use of tampons. Menstruation blood produces a special odor when it contacts with air. In tampons however the odor is eliminated since the blood does not contact with air. Although vaginal tampons make life easier in menstruation periods and do not pose risks when used appropriately, they may cause life threating situations when used incorrectly. For example, life threatening diseases such as septic shock caused by the bacterium Staphylococcus aureus may occur due to the blood waiting too long in the vagina. The bacteria at the genital region rapidly proliferate in septic shock and the toxins they produce pass to the blood of the user. Tampons should be frequently changed in order to prevent this situation. However, the best precaution that can be taken is to have the tampons possess microbial growth preventing properties.

Since babies cannot control their bladders and bowel movements, they urinate and defecate uncontrollably. To this end, nowadays paper based disposable baby diapers are used. Feces of babies have an irritating effect on the sensitive skins of babies. The thin fat layer on the surface of the skin irritates the skin as it passes moisture and feces. Occasionally irritations called diaper rashes, which appear bright red, occur on the babies' bottoms. Increase of heat and moisture on the irritated skin create a suitable medium for reproduction of some microorganisms and thus the rash gets “infected”. The factor which is accepted as the reason for development of rash on the skin is the ammonia released under the effect of the bacterium Bacillus ammoniagenes which breaks down urea. In the studies that were conducted, Staphylococcus aureus were found on the skin area where rash is observed; however, whether this bacterium is the primary reason or a secondary reason of the rash has not yet been clarified. In 85% of the findings which is a substantial amount, the species Candida albicans was detected at the rash area. Similar to the bacterial case, it has not yet been clarified whether Candida albicans infection is the primary or secondary cause of the rash formation. However, it has been identified that either of these microorganisms causes the infected rash. Problems encountered in baby diapers can also occur in patient diapers.

There are studies in the state of the art on the antimicrobial properties of some boron compounds. Bailey et al. (1980) found, with the experiments they conducted, that boric acid has antibacterial activity on enteric bacteria. Antimicrobial agents containing boron were tried on gram negative bacteria (Escherichia coli and Proteus mirabilis) and were observed to be effective.

Additionally, in a study by Benkovic et al (2005), it was observed that boric esters have a broad spectrum antibacterial activity. Results of their study reveal that boric esters inhibit DNA methyl transferase in gram negative and positive bacteria.

Reynold et al. (2007) indicated that lipophilic 2,4-diamino-6-methylpyrimidine antifolate compound, which comprises two different borons, has a moderate level antibacterial activity against the bacteria Mycobacterium avium and Lactobacillus casei. In addition, it is shown that some boron derivatives have antifungal activities.

A study by Qin et al. (2007) showed that potassium tetraborate has an inhibitory effect on micelle growth of Penicillium expansium. It was determined that 0.1% concentration of potassium tetraborate is the minimum concentration preventing micelle growth. Qin et al. (2010) also searched for the effects of potassium tetraborate on Botrytis cinerea which is the pathogen leading to gray mold disease. They showed that they could control this mold causing disease on the grapes by using potassium tetra borate with 1% concentration. However, in none of the said studies were developed boron added antimicrobial sanitary pads, tampons, baby diapers and patient diapers.

A study by Hennessey (2006) showed that a 10-minute exposure of various bacterial strains to 0.02% chlorhexidine solution lead to 99.99% inhibition of these microorganisms.

A study by Regos et al. indicates that triclosan is 10 to 100 times more effective than hexachlorophene on Escherichia coli, Klebsiella edwardsii and Salmonella spp. but is less effective on streptococci, micrococci, and Propionibacterium acnes. The study also revealed that even the low-concentration of triclosan had a broad spectrum effect on both gram negative and gram positive bacteria, especially on Proteus vulgaris, Salmonella spp., mycobacteria and anaerobic bacteria.

In a study by Bernstein et al (1990), activities of 0.12% chlorhexidine gluconate containing mouthrinse (Peridex) against herpes simplex virus (HSV) related with tooth decay, cytomegalovirus (CMV), influenza A, parainfluenza, polio, and hepatitis B (HBV) virus were researched and the results indicated that it was effective against all the viruses, except polio virus, within 30 seconds.

A study by Bailey and Longson (1972) indicates that while 0.02% chlorhexidine gluconate reduced the virus titration of Herpesvirus hominis by more than 99% at the end of a 90-minute exposure at room temperature, it remained ineffective against poliovirus and adenovirus.

In the US patent documents numbered U.S. Pat. No. 4,896,768 and U.S. Pat. No. 6,488,948, in the state of the art, antibacterial sanitary pads were developed. Additionally the US patent document numbered U.S. Pat. No. 4,405,323 discloses about development of an antibacterial tampon to prevent septic shock. However, it was not indicated whether the said products have any effect on fungi, yeasts and viruses.

The above-mentioned inventions do not disclose antifungal, anticandidal and antiviral activities; the said applications are intended only against bacteria.

DETAILED DESCRIPTION OF THE INVENTION

In all of the tests standard hygienic products not containing boron compounds are used as the negative control.

Within the scope of the invention; applications were made on hygienic sanitary pads, tampons, baby diapers, patient diapers by using sodium borate ((Na₂O)(B₂O₃)₅.10H₂O), zinc borate (2ZnO.3B₂O₃.3.5H₂O), sodium perborate tetrahydrate (NaBO₃.4H₂O), borax pentahydrate (Na₂B₄O₇.5H₂O) and disodium octaborate tetrahydrate (Na₂B₈O₁₃.4H₂O) boron compounds and glucopon, chlorhexidine gluconate, triclosan; and thus hygienic products with new properties are obtained.

Experimental Studies Antimicrobial Tests Modified Disc Diffusion Method

Standard NCCLS disc diffusion method [21] was used by being modified in order to determine the antimicrobial activity of boron compounds on each microorganism that is being tested. The 100 id solution containing 10⁸ cfu/ml of bacteria, 10⁶ cfu/ml of yeast and 10⁴ spore/ml of fungi was prepared with new cultures and was inoculated with spreading method on Nutrient Agar (NA), Sabouraud Dextrose Agar (SDA) and Potato Dextrose Agar (PDA), respectively. 20 μl of sterile water was dropped on the empty discs and it was separately immersed into pulverized zinc borate, sodium borate, sodium perborate tetrahydrate, borax pentahydrate, disodium octaborate tetrahydrate. The discs coded with zinc borate, sodium borate, sodium perborate tetrahydrate, borax pentahydrate, disodium octaborate tetrahydrate were placed in inoculated petri dishes. 20 μl sterile water dropped empty discs were used as negative control. As for positive control, Ofloxacin (10 μg/disc) and nystatin (30 μg/disc) were used for bacteria and fungi, respectively. The petri dishes, which were inoculated and on which modified disc diffusion method was applied, were kept at 36±1° C. for bacteria for 24 hours and for yeasts for 48 hours and at 25±1° C. for fungi for 72 hours. Antimicrobial activity against microorganisms tested with modified disc diffusion method was assessed by observing the inhibition zone (zone where microorganisms do not grow). Antimicrobial activity test results of the tested boron compounds are summarized in Table 1. All tests were repeated at least twice.

Method of Obtaining Hygienic Products Containing Boron Compounds, Chlorhexidine Gluconate, Triclosan

Zinc borate, sodium borate, sodium perborate tetrahydrate, borax pentahydrate and disodium octaborate tetrahydrate of different concentrations (0.05-50 mg/cm²) are mixed with SAP (superabsorbent) material. Then, they are dispersed to the layer of the baby diapers and pads between the water absorbent inner surface and impermeable outer surface. The said mixture is dispersed homogeneously to the absorbent inner layer of the tampon.

In order to increase absorbance of the surface contacting the skin and to provide antimicrobial property;

-   -   for 1000 g solution, 0.3 g triclosan is mixed in 70 g Glucopon         215 CS UP©, until it becomes homogenous,     -   75 g 20% chlorhexidine gluconate is added to the mixture and the         solution is homogenized by the help of a homogenizer,     -   854.7 g distilled water is added to the obtained solution and         mixed for 1-1.5 hours,     -   pH value of the solution is brought to 5-7 by the help of citric         acid or acetic acid.     -   The prepared solution is transferred to a holding tank, and the         textile material, on which it will be applied, is immersed         therein so as to completely cover the surface; it is kept         therein for 5-10 minutes and then is completely dried at 25-90°         C.

Antimicrobial activity tests of sections of the developed baby diapers, tampons, sanitary pads and patient/adult diapers prepared at sizes of 4×4 cm and 1×1 cm were performed via the below mentioned methods.

Antimicroblal Tests

Antimicrobial activity tests of sanitary pads, tampons, baby diapers, and patient/adult diapers prepared as described above with zinc borate, sodium borate, sodium perborate tetrahydrate, borax pentahydrate and disodium octaborate tetrahydrate were performed simultaneously by two different methods.

-   -   In the first test method; isolates from the bacteria Escherichia         coli, Staphylococcus aureus, Pseudomonas aeruginosa; the yeasts         Candida albicans and Candida glabrara and the fungi Aspergillus         niger, Botrytis cinerea, Fusarium oxysporum, Penicilliun         vinaceum, Penicilliurn expansum were inoculated on petri dishes         containing suitable media (NA, SDA and PDA respectively).         Absorbent parts of the boron added hygienic products with         hydrophilic surfaces containing chlorhexidine and triclosan and         prepared in a size of 1×1 cm were placed on the inoculated petri         dishes such that they touch the medium surface. The inoculated         petri dishes were incubated for 24 hours for bacteria and 48         hours for yeasts at 36±1° C. and 72 hours for fungi at 25±1° C.         Antimicrobial activities of hygienic products were assessed by         observing the inhibition zone (zone where microorganisms do not         grow) formed around the samples on which application is made.     -   In the second method, the boron-containing or not-containing         pad, tampon and baby diaper surfaces having a size of 4×4 cm         placed in empty petri dishes are contaminated by 100 μl of the         solutions (containing 10⁸ cfu/ml bacteria, 10⁶ cfu/ml yeast and         10⁴ spore/ml fungi) prepared from the fresh media prepared         within the buffer solution. The contaminated hygienic products         were incubated at 36±1° C. for bacteria and yeasts, and at         25±1° C. for fungi. It was determined whether there was         microbial growth on the surfaces of the tested hygienic product         surfaces by performing regressive Isolation In intervals of 1, 3         and 6 hours.

According to the pretesting results, it was determined that among the concentrations that were used, 4 mg/cm² zinc borate, 4 mg/cm² sodlam borate, 5.5 mg/cm² sodium perborate tetrahydrate, 5.5 mg/cm² borax pentahydrate and 5.5 mg/cm² disodium octaborate tetrahydrate gave the most effective antimicrobial (antifungal, anticandidal and antibacterial) results. Then the above summarized experiments were continued for only the most effective concentrations of boron compounds with 3 repetitions. The results are summarized in Table 2.

Experimental studies were carried out with certain fungi, yeast and bacteria species.

Among these microorganisms, the bacteria were Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa.

The yeasts used in the experimental studies were Candida albicans and Candida glabrata and the fungi used in the same were Fusarium oxysporum, Botrytis cinerea, Aspergillus niger, Penicillirm vinaceum and Penicillium expansum.

Antiviral Tests Antiviral Activity Tests of Chlorhexidine Gluconate;

In order to produce Human adenovirus type 5 Adenoid 75 strain and Poliovirus type 1 Chat strain virus and to carry out the experiment, a complete layer of HEp-2 cells (ATCC CCL-23), which are human monolayer tumor cells, were used. For determining virus titration, reference Human adenovirus type 5 Adenoid 75 strain and Poliovirus type 1 Chat strain were inoculated by making serial dilutions to HEp-2 cells, and by taking as basis the virus dilution that produces a cytopathic effect visible in invert microscope, virus titration was computed by using Spearman-Karber method. In order to determine Sub-Cytotoxic concentration of Chlorhexidine gluconate, Chlorhexidine gluconate was 10-fold serially diluted with Eagle's minimum essential medium (MEM) and non-toxic concentration was detected in the cell culture and non-toxic concentration was used in the antiviral tests. For the controls, MEM inoculated HEp-2 cells, full layer HEp-2 cells wherein Chlorhexidine gluconate could not be added, 10-fold diluted reference virus titration control, formaldehyde control and controls containing toxic concentrations of Chlorhexidine gluconate were used as negative control instead of the virus.

Preparation of Cell Culture Medium and the Chemicals

MEM medium:

10% serum (FBS) containing enzymes, hormones and growth factors for the cells to adsorb to the surfaces and proliferate; and 40 IU/ml penicillin, 0.04 mg/ml streptomycin, 0.5 mg/ml glutamine to prevent fungi and bacteria contamination; and 1% sodium bicarbonate as a buffer solution were added therein. (FBS: Inactivated and without mycoplasma), (Sodium bicarbonate: Sterile 7.5% solution)

Medium Used in Virus Inoculation:

The medium included 1% antibiotic (Penicillin, Streptomycine, Amphotericin B) in order to prevent fungi and bacteria contamination, and 1% sodium bicarbonate as a buffer solution. FBS serum was not added to this medium.

Hard Water Preparation:

-   -   Solution A: 19.84 g nonaqueous magnesium chloride (MgCI2) or         hydrated magnesium chloride and 46.24 g nonaqueous calcium         chloride (CaCl₂) or hydrated calcium chloride in water are         dissolved in water of the same equal amount. It is diluted to         1000 ml and autoclaved.     -   Solution B: 35.2 g sodium bicarbonate (NaHCO₃) is dissolved in         water and diluted to 1000 ml. It is filtered (mesh size should         be 0.22 μM).

Hard Water:

-   -   6.0 ml Solution A and 8.0 ml solution B are added to 600 ml         water.     -   It is stirred and diluted to 1000 ml.     -   pH value of the hard water should be 7.0±0.2.     -   40 g/l sodium hydroxide (NaOH) (1 mol/l) or hydrochloric acid         (HCI) (1 mol/l) is used to adjust pH value.     -   It should be prepared in sterile conditions and used within 12         hours.

Preparation of Clean and Polluted Media

Clean medium; 0.3 gr Bovine Serum Albumin Fraction V is dissolved in 100 ml sterile water. The solution that is obtained is sterilized by being passed through a filter with mesh size 0.22 μM.

Polluted medium: sheep erythrocyte and BSA are used for the polluted medium. 3 g BSA is dissolved in 100 ml sterile water and filtered. 3 ml sheep erythrocyte was completed to 97 ml BSA.

Erythrocyte; 8 ml fresh sheep blood was rotated at 800 G for 10 minutes and then its supernatant was removed; upon adding 8 ml phosphate buffer salt (PBS), pipetting was performed and it was again rotated at 800 G for 10 minutes. This procedure was repeated three times.

Analysis

Firstly, liquid chlorhexidine gluconate was solid serially diluted with the cell culture medium (MEM) and its non-toxic concentration in cell culture was calculated. 8 ml of the chlorhexidine gluconate that will be tested was mixed with 2 ml hard water. The obtained solution was serially diluted (dilution step 1:10) with MEM and incubated in 96-well monolayered cells. The microscopic changes that occurred were recorded. Concentrations that showed cytopathic effect (CPE) were determined. Chlorhexidine gluconate and formaldehyde CPE values were compared. After determining non-toxic concentration of chlorhexidine gluconate on the cells, the effect of chlorhexidine gluconate on virus titration as a result of 1-60 minutes application periods in clean and polluted media was studied. For the controls, MEM inoculated HEp-2 cells, fill layer HEp-2 cells wherein Chlorhexidine gluconate could not be added, 10-fold diluted reference virus titration control, formaldehyde control and controls containing toxic concentrations of Chlorhexidine gluconate were used as negative control instead of the virus.

Taking as basis the virus dilutions wherein cytopathic effect that is visible in invert microscope is formed, virus titration was calculated as TCID₅₀ value by using Spearman-Karber method.

According to TS EN 14476 (MARCH 2007) standard, disinfectants should reduce virus titration by 4 or more logs for their antiviral activities.

Antiviral Activity Tests of Glucopou Solution:

8% Glucopon which was used for making the surfaces hydrophilic was tested on Human Herpes simplex virus type 1 (HSV-1) MachIntyre strain as described above. Taking as basis the virus dilutions which are seeded by performing serial dilutions to Vero (ATCC CCL-81) cells and wherein cytopathic effect that is visible in invert microscope is formed, virus titration was calculated as TCID₅₀ value by using Spearman-Karber method.

Antiviral Activity Tests of Mixture of Chlorhexidine Gluconate, Glucopon and Triclosan:

As mentioned before, a solution containing Chlorhexidine gluconate, Glucopon and Triclosan which will be applied to a surface was prepared as follows: for 1000 g solution, 0.3 g Triclosan was mixed in 70 g Glucopon until it became homogeneous, then 75 g 20% Chlorhexidine gluconate was added and the solution was homogenized by the help of a homogenizer and upon adding 854.7 g distilled water, the solution was stirred for 1-1.5 hours. pH value of the solution was made ready by being brought to 5-7 by the help of citric acid or acetic acid. As sated above, the antiviral tests tested antiviral activity against the Human adenovirus type 5 Adenoid 75 strain, Poliovirus Type 1 Chat strain and Human Herpes simplex virus type 1 (HSV-1) MacIntyre strain viruses.

Antiviral Activity Tests of Fabric Surfaces on which the Mixture of Chlorhexidine Gluconate, Glucopon and Triclosan was Applied:

2 cm×2 cm surfaces were cut out from different points of the textile surfaces on which the solution was applied and were placed on 0.5 cm diameter vials. 1 ml virus stock was passed over the surfaces with specified areas. Then the virus stock collected in the vials was sterilized by being passed through a filter with mesh size 0.22 μM. The above-mentioned virus experiment procedure was tested against 3 virus strains for this solution.

Experimental Results

According to the antimicrobial activity test conducted by modified disk diffusion method, it is determined that boron compounds have an effect of preventing growth of all of the tested microorganisms (bacteria, yeasts and fungi). (Table 1)

Hygienic products (sanitary pads, tampons, baby diapers, patient/adult diapers) of 1×1 cm containing or not containing zinc borate, sodium borate, sodium perborate tetrahydrate, borax pentahydrate and disodium octaborate tetrahydrate were prepared in in vitro conditions. Antimicrobial activities of the prepared products were tested by using bacteria (Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa), yeast (Candida albicans, Candida glabrata) and fungi (Fusarium oxysporum, Botrytis cinerea, Aspergillus niger, Penicillium vinaceum, Penicillium expansum) isolates. According to the obtained results, it was determined that hygienic products containing zinc borate, sodium borate, sodium perborate tetrahydrate, borax pentahydrate and disodium octaborate tetrahydrate have antimicrobial activity on all of the tested microorganisms while it was observed that the hygienic products with no additives did not show any antimicrobial activity (Table 2).

As a result of the experimental studies, while no growth was observed in sodium borate added sanitary pad and tampon, fungal growth and sporulation were detected in hygienic products with no additives (FIG. 1a, 1b . FIG. 3a, 3b ).

While no fungal growth was observed in zinc borate added sanitary pad and tampon, fungal growth and sporulation were detected in hygienic products with no additives (FIG. 2a, 2b ).

Since the 10% and 1% suspensions of the tested chlorhexidine gluconate showed cytopathic effect on the cells in the cell culture, the lowest ratio of the said chlorhexidine gluconate which does not show cytopatlic effect, i.e. 0.1%, is used in this study. As a result of the calculations made at the end of the test, it was determined that chlorhexidine gluconate caused at least 4 log reduction in virus titration against Human adenovirus type 5, poliovirus type 1 and herpex simplex (Table 3, Table 4 and Table 5) at all experiment conditions as a result of application at room temperature (20° C.), in clean and polluted media and within 1 and 60 minute application periods.

As a conclusion: these experiment results show that chlorhexidine gluconate is 99.9% active against Human adenovirus type 5 virus, 99.9% active against Poliovirus Type 1 virus and 99.9% active against Herpex simplex virus when used directly without being diluted at room temperature (20° C.) within 1 and 60 minute application periods.

Since the tested 8% Glucopon solution showed cytopathic effect on the cells in the cell culture, the lowest ratio of the said Glucopon which does not show cytopathic effect, i.e. 0.1%, is used in this study. As a result of the calculations made at the end of the test, it was determined that Glucopon did not cause any reduction in virus titration against Herpex simplex virus (Table 6) at the experiment conditions as a result of application at room temperature (20° C.), in clean and polluted media and within 1 and 60 minute application periods.

It was determined as a result of the antiviral activity tests that the mixture of Chlorhexidine gluconate, Glucopon and Triclosan caused at least 4 log reduction in virus titration at all experiment conditions (Table 7, Table 8 and Table 9) as a result of application in clean and polluted media and within 1 and 60 minute application periods.

It was determined as a result of the antiviral activity tests that the fabric surfaces on which the mixture of Chlorhexidine ghconate, Glucopon and Triclosan was applied caused at least 4 log reduction in virus titration at all experiment conditions (Table 10, Table 11 and Table 12) as a result of application in clean and polluted media and within 0 and 60 minute application periods.

In accordance with the TS EN 14476 (MARCH 2007) standards of Turkish Standards Institute (TSE), it is accepted that, when used with any one of the methods of washing, wiping, impregnation (wetting/immersing), this product, whose virucidal activity against Human adenovirus type 5 which is a DNA model virus sample is researched, shows the same virucidal activity against other enveloped or non-enveloped DNA viruses which cannot be practically tested in laboratory such as HBV provided that it is used at least at the above mentioned solubility and periods: and that this product, whose virucidal activity against Poliovirus Type 1 which is an RNA model virus sample is researched, shows the same virucidal activity against other enveloped or non-enveloped RNA viruses (e.g. Ebola, Mers, Sars, etc.) which cannot be practically tested in laboratory such as HCV and HIV provided that it is used at least at the above mentioned solubility and periods.

Irritation tests were performed according to OECD/OCDE 404 method for the prepared antimicrobial products in order to find out whether they cause any irritation on skin. According to the test results, it was observed that no irritation occurred within a period of 14 days.
